We just noticed that LicenseChooser.js 0.95 and earlier had the wrong help
text for "Share Alike". Due to a copy and pasting error, if you hold your
mouse over "Require Share Alike" icon in the old demos (e.g.
http://labs.creativecommons.org/demos/jswidget/tags/0.95/example_web_app/), you will see a copy of the help text that corresponds to "Prohibit Commercial Use".

Eek.

LicenseChooser.js 0.96, as you can see at http://labs.creativecommons.org/demos/jswidget/tags/0.96/example_web_app/, fixes this problem.
